TYPE-WRITER.

SPECIFICATION forming part of Letters Patent No. 685,7 2, dated November1901- Application filed January 13, 1899. Serial No. 702,054. (Nomodel.)

To all whom it may concern:

Be it known that I, FREDERIC W. HIL- LARD, a resident of Tottenville,county of Richmond, and city and State of New York, have inventedcertain new and useful Improvements in Type-Writers, of which thefollowing is a specification.

My invention is an improvement in typewriting machines, which relates toa simple and efficient means for shifting the typeheads upon thetype-bars in order to eifect the printing of a plurality of type withthe same typebar. This improvement is designed more especially for useon machines adapted for writing on bound books. On such machines thepaper is placed upon a fiat platen or printing-surface incontradistinction to the cylindrical platen of the ordinarycommercial-letter writer. The invention is, however, adapted to machineswhether the platen is provided with a flat printing-surface or a curvedone.

Myinvention also comprises the various details of construction hereinshown and described.

In the accompanying drawings, which form a part of this specification,Figure l is a sectional side elevation of the machine, showing some ofthe typo-bars and type-heads and the mechanism for shifting thetype-heads on the type-bars from one printing-base to another. Fig. 2 isa detail of a type-head of Fig. 1. Fig. 3 shows a modified type-bar withits typehead and several other parts which are operatively connectedtherewith. Fig. 4 is a detail of the type-head of Fig. 3. Fig. 5 is asectional detail of a portion of the type-bar and of the pivot of Fig.3. Fig. 6 isa side View of the parts shown in Fig. 5.

The carriage A is mounted for lateral. movement upon frame 13 and issupported thereon by rollers W W at the front and at the rear, whichrest upon guide rails g g, fixed to frame B. The type bars T arepivotally mounted on hangers T, so that they can be moved from thebuffer-ring b to the platen for printing. The hangers T are arrangedconcentrically around the circular opening in the carriage A, so thatthe type will all print at a common center. I have only shown two of thetype-bars, one at the front and one at the rear of the machine; but Iwish to have it understood that there is a circular opening in thecarriage and that the type-bars extend entirely around this circle. Thetype-heads H are pivotally connected to the type-bars by the type-headscrews 0. Each type-head comprises two type, an upper-case type u and alower-case type Z. Both of these type are formed integral with thetype-head, and each of them is provided with a shank u and Z,respectively, which connect them with the main body of the type-head.Some of the functions of these shanks u and Z are to correct anyimperfection in the positioning of the two type it and Z relatively toone another upon the type-heads. The shanks are so made that they can bebent and twisted so as to establish the proper distance between the twotype, and they can be cut with pliers in order to throw the type upontheir feetthat is to say, to cause it to strike the paper evenly.

The type-heads are controlled in both printing positions on thetype-bars by means of type-head spring S, the type-head being providedwith a tapered projectione and the typehead spring being provided with amounted indentation j for engagement therewith. The projection t' andthe indentationj are so positioned relatively one to the other that thepoint of the projection i shifts across the point of indentation y whenthe type-head is shifted from one printing position to another, and theinclined faces on both sides of the indentationj upon spring S engagewith the corresponding inclined faces on the sides of the projection ito control the type-head on the type-barin each printing position. Thetypeheads are each provided with the bankingfaces m and n, and eachtype-bar is provided with corresponding banking-stops m and n,

which engage with the banking-faces m and n and positively limit thethrow of the typeheads upon the typ-bars in either direction.

The method in which I construct the modified type-bar T of Fig. 3 is asfollows: I first punch the bar out of sheet metal. Then I force themetal comprising the banking-stops m and it out of the body of thetype-bar, forcing this metal half-way through, so that it may comprisethe banking-stops m and n, but only partially through, so it stillremains IOO an integral part of the type-bar. I then punch a holethrough the pivotal portion of the type-bar and a hole through the lowerextremity of the bar to receive one end of the wire connecting thetype-bar withthe corresponding key-lever. Through the pivotal hole Iinsert a short piece of wire and rivet this wire on each side of thehole. This forms the body d, of sufficient thickness to securely holdpivot s of the type-bar. The type-bars are connected with the key-1evers V by means of the connecting-wires o o, and at the opposite end ofthe key-levers the finger-keys K K are provided in the usual manner. Thetypebars are normally held in a perpendicular position, with thetype-heads resting in buffer b, by means of key-lever springs V V.

The operation of my type-bars and typeheads is as follows: Mechanism isprovided for shifting the type-heads from the lowercase position to theupper-case position on type-bars, which I will now describe. Shiftkeylever R is connected by means of shiftkey-connecting wire L totherocker-shaft arm 'M, which is rigidly fastened to one end of therocker-shaft N. To the opposite end of the rocker-shaft N therocker-shaft arm 0 is rigidly fastened and operatively connected by apin (not shown) with disk plunger-rod P. The disk plunger-rod isnormally held in a raised position by means of shift-spring Q,

thereby holding the tripper-disk D normally in the raisedposition shownin dotted line in Fig. 1. Fig. 1 shows the parts of the machine withshift-key lever R depressed and the disk D lowered into operativeposition to effect the shifting of the type-head from the'lower-caseprinting position to the upper-case printing position. The tripping endCtiS of such length from the pivotal center of the type-head that whenengaged by disk D upon the depression of shift-keylever B it will forcethe typehead to be swung on its pivot far enough for the point of theprojection 'i to move across the point of indentation j. After thetypehead has been swung thus far the pressure of the spring S againstthe upper inclined face of the projection 'i will complete the movementof the type-head until the banking-face m engages the banking-stop m,which limits the movement of the type-head on the typebar. When thetype-bar is in position for printing with the upper-case type,the'tripping end a swings :with the type-bar free of disk D. Thereforewhen the type-head is in the upper-case printing position upon the re-'lease of the type-key. K the type-bar will swing up past disk D untilthe type-head engages with bufier b, and then the pressure of thetripping end a against buffer 1) shifts the type-head back tolower-caseprintingposition,

with the banking-face n in engagement with banking-stop n. When theshift-key lever B and the tripper-disk D are in their raised positions,the type-heads are not shifted on the type-bar when the printing-keys KK are operated. Thetype-heads remainatalltimes while in the buffer 1) inthe lower-case print? 1 ing position; but when the shift-key leverR isdepressed, together with disk'D, each typehead will be shifted bycontact of trippingjend a with disk D from lower-case printing 2;position to upper-case printing position dur-i ing the depression of theprinting-key, and"? Y i will then be returned to lower-casc-printing;position upon the release of the key by con-,

tact of tripper end a. with bufier 'b.

I do not in this application make any claim to the above-describedtripping and control- 0? ling mechanism for the type-head except intheir combination with the integral type-head 1' herein described, assuch tripping and controlling mechanism form the subject-matter;

of and are claimed in my application filed May 25, 1897, seriallynumbered 638,007,111-
